Think of the routed protocol as the truck that is used to transport the final cargo. Think of the routing protocol as the brain of a human, depending on the destination the cargo is to reach tok 136Chapter 5 Routing Protocols **" 05choose the correct transmission route for the truck. There are direct, static, and dynamic routing protocols, as shown in Figure 5-1-2. Dynamic routing protocols are subdivided into IGP (Interior GatewayProtocol) and EGP (ExteriorGatewayProtocol) depending on the AS (Autonomic Systems) in which they are located, where an autonomous system is a network with a unified IGP protocol refers to a network with a unified management authority and a unified routing policy.IGP protocols are divided into distance vector routing protocols and link state routing protocols. BGP protocols also belong to dynamic routing protocols. BGP protocols require a high level of configuration personnel, and most people will not encounter them in the actual working environment.RIP oldest routing protocol c distance vector IGRP Cisco private routing protocol, now largely obsolete, no longer covered in CCNA EIGRP extended IGRP protocol, Cisco private, advanced distance vectorInterior Gateway Protocol - OSPF is the most used routing protocol in the interior of the Routing State, Dynamic Routing Protocol IS-IS is rarely used domestically, mainly BGP, which is not normally used within the enterprise and is not covered in the CCNA% test Routing Protocol: Direct Routing Protocol: Routing of the direct connection port of the router, the router automatically generates the route of the direct connection port Static Routing Protocol: requires manual care by the administrator Figure 5-1-2 Routing Protocols nNote: EIGRP is an advanced distance vectoring protocol with features of both distance vectoring and link-state routing protocols and is sometimes referred to as a hybrid protocol. Bo> 5.2 Direct Connect Routing** Based on the way routers learn routing information, generate and maintain routing tables, routes are classified as: direct routing (Connect routing) > static routing (Static routing) and dynamic routing (Dynamic routing) o Direct routing is discovered by data link layer protocols and is the path to the network segment where the router's interface address is located, the The route information does not need to be maintained by the network administrator or calculated by the router through some algorithm, as long as the interface is active, the router will fill in the routing table with the route information of the segment where the directly connected interface is located. Using routers Rl, R2, and R3 in the CCNA rack, the connections and IP address assignments between them are shown in Figure 5-2-1. The experiments in this chapter are completed in the topology shown in Figure 5-2-1.

In future experiments, whenever an Ethernet interface is involved, CDP will be turned off.

However, the route for the Fa0/0 interface (13.1.1.0/24) and the route for the S1/2 interface (8.8.1.0/24) are not found.(8.8.8.0/24), because the router automatically generates routes to activate the port, and although the FaO/O interface is configured with an IP address, it does not use the
